WHEEL CONSTRUCTION.

Specification of Letters Patent.

Patented Augi 2 4,. rac a Application filed January 27, 1909. Serial No. 474,471.

To all whom it may concern:

Be itknown that 1, ROBERT B. 7001)- WORTH, of- Pittsburg, Allegheny county,

Pennsylvania, have invented a new and useful Wheel Construction, of which the following is .a full, clear, and exact description, reference being had to the accompanyin drawin s formin art of this s ecifica- 'tion, in Wh1ch Figure 1"is a side elevation partly in section of a wheel constructed in accordance with my invention; Fig. 2 is an end elevation partly in section of the same; Fig. 3 is a sectional end elevation on the line II IIII of Fig. 1; Fig. 4 is a detail transverse section through the rim of the brake wheel,

showing the removable segmental fillers se-.

cured to the rim of the wheel; Fig. 5 is a similar view showing the grooved wooden fillers secured to the metal rim of the rope drive of the wheel.

My invention relates to the construction of wheels and .it more particularly relates to vthe construction of bull wheels and calf wheels used on rigs employed for drilling wells.

The object of my invention is to provide an improved wheel construction in which a strong and durable wheel is obtained which is light in weight and is of greatly increased strength.

Another object of my inventionis to provide a wheel construction in which standard rolled metal shapes are employed in making the wheel.

In the drawings, 2 represents the shaft of a bull orcalf wheel which is preferably formed of a standard wrought iron or steel pipe or tube and 3, 3 represent the trunnions of the shaft 2 which are removably secured to its ends by means'of the screw threaded bolts 4. A rope driving rim 5 which is formed by bending a standard rolledshape or channel of I beam form to the desired curvature, is secured to the outer end of the spokes 6 of the wheel. The spokes6 are formed as shown of standard rolled beam," shapes although channels or other standard shapes may be employed,

which are fastened tothe rim 5 by means of angle connections 7 these connectionsbe ng preferably made from a section of standard rolled steel angle. The inner ends of the spokes 6 are riveted or otherwise secured to the vertical legs 8 of the annular flange rings 8, the other legs 8 poftheseirings"be p,

.ing riveted or otherwlse secured n and to the shaft 2 by similar a gering,

length between the rope wheel the pipe 9., forming the shaftgfor' "h At the opposite end of the shai I wheel having a similar rim powers also is preferably formed fronpabe metal channel. The spokes lldof heel are made from rolled steel: shapes preterab of I beam form, and are securedlto the rink 9 by means of similar connectingfangl'cs To secure the proper bearingsurface for '1 the brake band Wheel, the fspacebetween up flanges on the channel rim oni'thc bra'kc band end of the wheel construction is lined qe with segmental fillers 11 of .too lh e wooden tillers are made exact to t'en iplet'j-an'df are secured in place on the channel rinilby-Q means of screw-threaded bolts 9 il l S SllO\\ 'l l f in Fig. 4. The rim of the drivin wl endfis of the apparatus is also provided and mental wooden fillers l2 'which areisecured 'in place in a similar manner t9, llQTSGIOI 1 9 1;. channel rim of the brake wheel endfofft'he wheel construction. In the drivingg w the wooden fillers 12 are shaped jse form a series of annulanv -sh aped 'gro for the driving ropes usedin actuating'such wheels. The grooves shown are made'in" the preferred form for use with manila" dri'vi-n ropes and where wire ropes'flare useo stead, the form of the groovefwillgbeco spondingly changed. i I

Secured to the shaft Qjat a p' int' in ts till i the brake wheel, is a plnralityjof outwai extending arms or spokes 13 which divide the length of the shaft 2 into two parts, one being used for coiling the slack of the drilling rope, the other being used for the p01- tion oft-he rope actually employed at any particular time in the drilling of the wells. The spokes or arms 13 are secured to the shaft 2 by means of the flange 14 which is formed from a rolled metal angle into the desired size and shape, the vertical leg 14 of this angle being secured to the arms 13 in thesame manner as the spokes v(3 on the 'band wheel.

In order to turn the bull wheel by, hand, the usual handles 15 are provided, in this case the'handles being applied to the rim of the wheels in a novel manner, being formed from apiece of metal pipe which is securely held in place on the rim of the wheel by 119 "means of the bolts 16 as is best shown in Figs. 4 and 5.

The advantages-of my invention will be appreciated by those skilled in the art. By

5 the use-of standard rolled metal shapes, a wheel construction is provided which is of very. -largely increased strength and which is; ofmuch less weight than the ordinary ,woden construction. The apparatus is ;'-'.10 sim 1e and can be easily and cheaply made.

2. A wheel having a hollow tubular shaft,

7' arched metal rim having peripheral'flanges, rolled'metal spokes between the rim and .shaft, andangle connections for securing .-'25'the'spokes to the rim and shaft, and segmental wooden fillers between the peripheral flanges of the 'rim,. sai-d fillers being removable; substantially as described.

.' V. 3. A wheel having-a hollow tubular shaft,

39' a rolled-metal rim having peripheralflanges, rolled metal spokes between the rim and fshaft, angle connections for' securing the jspokes to the rim and shaft, segmental f wooden'fille'rsbetween the peripheral flanges of the rim, and securing bolts for holding the wooden fillers in place on the rim, substantially as described.

4:. A wheel having a hollow tubular shaft," I atrolled metal rim having peripheral flanges,

140" rolled metal spokes between "the rim and shaft, angle connections ,for securing the spokes" to the rim. and shaft, segmental wooden fillers between the peripheral flanges "of the rim, and'securing bolts for holding 4 5;the wooden fillers in place in the rim, the

wooden fillers being independently removable; substantially as described.

5. A wheel having a hollow tubular shaft, trunnions secured to the ends of the shaft, a

rolled metal rim having peripheral flanges,

rolled metal spokes between the rim and shaft, and angle connections for securing the spokes to the rim and shaft; substan tially as described.

6. A bull wheel having a hollow tubular shaft, rolled .metal rims having peripheral flanges on opposite ends of said shaft, trunnions removably secured on the ends of said shaft, said wheel having metal spokes be tween the rims and the shaft and angle connections for securing the spokes to the rims and shaft; substantially as described.

7 A bull wheel having a hollow tubular shaft, rolled metalrims having peripheral flanges on opposite ends of said shaft, trunnions removably secured on the endsof said shaft; said wheel having metal spokes between the rims and the shaft, angle connections for securing the spokes to the rims and shaft, and a plurality of arms secured to the "shaft intermediate of the two wheel rims on the shaft; substantially as described.

8. A bull wheel havinga hollow tubular shaft, rolled metal rims having peripheral flanges on opposite ends of said shaft, trunnions removably secured to the ends of said shaft, said wheel having metal spokes between the rims and the shaft, angle connections for securing the spokes to the rims and shaft, a plurality of arms secured to the shaft intermediate of the-two wheel rims in the shaft, and handles secured to the rim of at least one of said wheels; substantially as described.
